Hire the Best Science Professionals

Need a Power BI or Tableau dashboard that actually drives decisions, not just looks nice? I'm a data analyst with 7+ years in fintech, SaaS, and e-commerce, building clean SQL and dbt models under dashboards that hold up under scrutiny. Most BI freelancers know one tool. I work fluently across Power BI, Tableau, Metabase, and Looker Studio, and I build the SQL/dbt layer underneath rather than just connecting to whatever data exists. My fintech background (BNPL specifically) means I understand reconciliation, audit trails, and the gap between accounting and product metrics that most analysts miss entirely. Power BI: DAX measures, row-level security, Power Query data prep. Tableau: calculated fields, LOD expressions, visual storytelling. Metabase: self-serve internal analytics and customer-embedded dashboards with row-level sandboxing. Looker Studio: GA4, Google Ads, Search Console, and Meta Ads blended into one report. Data layer: SQL and dbt models on BigQuery, Snowflake, or Postgres. Internal LLM agents that answer warehouse questions in plain English from Slack or Teams, with SQL safety filters. Ongoing support: data model reviews, dashboard performance tuning, KPI definitions, dbt audits, and BI migrations. 100% Job Success on Upwork with a 5.0 rating across every completed contract. IBM and Google-certified in data analytics (IBM Data Analyst Professional Certificate, Google Data Analytics Professional Certificate). Previously drove a 7% MoM increase in payment success rates at Paymob and helped grow a user base tenfold to 200k+ customers through new reporting infrastructure at Bypa-ss. Message me with what your dashboard needs to support, and I'll reply with next steps within a day, often sooner.

Most AI projects die somewhere between the demo and production. I'm the engineer companies bring in so that doesn't happen. I'm Matthew, a Principal AI Engineer and Data Scientist at a Fortune 50 company, with 20+ years in enterprise data and an M.S. in Data Science from Northwestern University. On Upwork I take on a small number of projects where the goal is not "try AI" but "ship something that works, holds up under real users, and doesn't surprise anyone with a cloud bill." WHAT I BUILD ▸ RAG assistants over your documents, tickets, contracts, or knowledge base. Ingestion pipeline, chunking, embeddings, vector search, retrieval evaluation, guardrails, and a chat UI or API your team actually uses. Accuracy is measured, not assumed. ▸ AI agents and agentic workflows. LangGraph and MCP-based agents with tool calling, human-in-the-loop approval, retries, and observability. I will also tell you when an agent is the wrong tool and a plain pipeline will do the job for a tenth of the cost. ▸ Machine learning that changes decisions. Churn, propensity, lifetime value, forecasting, anomaly detection, recommendations. scikit-learn, XGBoost, LightGBM, PyTorch, with MLflow tracking and drift monitoring so the model still works six months from now. ▸ Data pipelines and analytics. ETL/ELT on Azure Data Factory, Databricks, Snowflake, and Spark. Data models, quality checks, and Power BI or Tableau dashboards that executives read without a translator. ▸ Private and low-cost AI. Fine-tuned small language models, on-prem and edge deployment, federated learning. Same results, a fraction of the API spend, and data that never leaves your network. RECENT WORK • Fortune 50 telecom: lead enterprise evaluation and rollout of LLM platforms, RAG, agentic architectures, and MCP, including the standards that decide what reaches production. • Fortune 50 telecom: semantic search and ranking on embeddings and vector search, shipped in customer-facing apps to lift relevancy and engagement. • Fortune 50 telecom: enterprise-wide customer quality-of-experience system using ML and GenAI for real-time Mean Opinion Score prediction, segmentation, and deployment planning. • Fortune 50 telecom: subscriber recommendation system (collaborative, content-based, hybrid), built with UX teams and measured on engagement. • Fortune 50 telecom: Monte Carlo forecasting model for Extended Reality adoption that guides multibillion-dollar network investment; led product managers and external vendors. • U.S. Patent 9,071,982: data mining algorithm integral to a $14 billion TDM-to-IP network conversion, used by Network, Finance, and Marketing. • Migrated a forecasting organization from on-prem to Azure and built an automated ensemble time-series system that replaced manual forecasts. HOW I WORK • You get a working plan before you pay for anything. Send me what you're trying to do and I'll reply with a straight answer on feasibility, what it will roughly take, and what I'd do first. • Fixed scope, weekly demos, no surprises. You see running software every week, not a status report. • Production means production: tests, evals, logging, docs, and a handoff your team can run without me. • Plain English. If you're not technical, that's fine. If you are, I'll happily get into the weeds. WHY CLIENTS PICK ME OVER A CHEAPER BID • I do this at Fortune 50 scale every day, so the expensive mistakes have already been made on someone else's budget. • U.S. patent inventor (9,071,982). I design systems, not just glue APIs together. • I cover the whole lifecycle: data, model, deployment, monitoring, business value. Most freelancers cover one link of that chain. • 20 years of translating between executives, engineers, and analysts.

I reply within 24 hours with an honest read on whether I can help, roughly what it would take, and what I'd do first. No charge, no pitch, and if I'm not the right person for it, I'll tell you who is.
